1 Claim.

(Granted under the act of March 3, 1883, as amended April 30, 1928; 3'70 0. G. 757) This application is made under the act of March 3, 1883, as amended by the act of April 30, 1928, and the invention herein described, if patented, may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.

The metal dip barrels at present used for collecting turpentine gum in the woods are equipped with heads which are held in place by a number of bolts, or which merely rest on the top of the barrel. Furthermore, these heads are not provided with any device for effecting their removal, and when they become smeared with gum, prying them off is a laborious task. Heads which are not bolted, but which merely rest on top of the barrel possess the obvious disadvantage of affording an opportunity for loss of gum. Realizing these difficulties, I undertook to develop a device which would serve to lock the head securely go in place on the barrel, and which would aiford a means for easy removal of the head when it is stuck on with gum. The device covered by my invention, which is more particularly hereinafter set forth, achieves these ends, and is at the same 5 time simple in both operation and construction. I attain these objects by the device illustrated in the accompanying drawing in which Figure 1 is a top plan view of the barrel head and Figure 2 is a side elevation thereof. 30 Similar numerals refer to similar parts throughout the several views.

The device consists of two sliding members I, 2 which are held in place on the upper surface of the barrel head 3 by straps 4 rigidly secured to 35 the upper side of the barrel head and beneath which sufiicient space is provided to allow free motion of the sliding members. The ends M of the sliding members I and 2 are curved to coincide with the curvature of the barrel top and are 40 also beveled to facilitate their sliding under the flange ordinarily provided on barrel ends. These sliding members and the respective associated straps are attached to opposite sides of the barrel head in such positions as to permit the sliding 45 members to be moved under or away from the barrel flange within the spaces under the straps when the head is placed in position on a barrel. Lateral motion of the sliding members I and 2 is prevented by the arms 5, 6, arms 5 being cut so 50 as to serve as guides against straps 4. Between sliding member 2 and the adjacent edge of the barrel head there are rigidly secured two parallel side plates I, perpendicular to the sliding members. Lever 8 is pivotally mounted between side 55 plates 1 as shown at 9. Arms 5 are bolted at one end of each to sliding member I inside and adjacent to the associated straps 4 as shown at H, and converge to points facing the opening between side plates 1, from which points arms 5 are extended in parallel relationship to each other 5 between the side plates 1 and pivotally attached to opposite sides of lever 8 slightly above pivotal mounting 9 and slightly off center of the lever toward the middle of the barrel head as shown at IU. Arms 6 are bolted to sliding member 2 as 10 shown at l2 and carried diagonally to points facing the opening between side plates 1 from which points they are extended in parallel relationship to each other between the side plates 1 where they are pivotally attached to opposite sides of 15 lever 8 below pivotal mounting 9 and slightly off center of the lever toward the adjacent edge of the barrel head as shown at [3.

To seal a barrel of gum, the head is dropped in place on the top of the barrel, and lever B is pushed down flat across the head, thereby causing sliding members I, 2 to move outward and to catch beneath the flange on the barrel end, thus holding the head securely on the barrel. The placing of pivots 9, l0 and I3, described above, is such as to prevent lever B from swinging out of its own accord when the barrel is rolled.

To remove the head from a barrel of gum, lever 8 is pulled up to the vertical position in which it appears in the drawing. A further pull on lever 3 8 will lift the head from the barrel, the lever being of sufficient length to provide the leverage necessary to move the barrel head when it is stuck with gum.

After the head has been removed from the barre], lever 8 serves as a convenient handle for lifting the head.

In the construction of my device, I have found that the material for the barrel head lock and remover may be wood, iron, steel or other metal, or any other suitable material. The lever mechanism may be fastened to the barrel head by means of rivets, bolts, welds, or other suitable means. The pivots on the movable parts may be bolts, rivets, rods fastened by cotter keys, or other suitable bearings. The parts of the lever mechanism may be formed by forging, casting, stamping or other method of manufacture.

Having thus described my invention, I claim:

A head for barrels having a flange at the upper end thereof, comprising a barrel head, two dual end locking plates slidingly mounted on the upper surface of the barrel head and in parallel relationship to each other, both ends of the locking plates being formed to engage said flange, two

spaced side plates rigidly secured adjacent to the edge of the barrel head parallel to each other to form a. space between them opposite the middle of the locking plates, a single lever pivotally mounted between said side plates, arms attached to the locking plate adjacent the side plates and extending and pivotally secured to the lever when in a vertical position, at a point below the first pivotal mounting, arms attached to the other locking plate and extending and pivotally secured to the lever when in a vertical position, at a point above the first mentioned pivotal mounting and means automatically to lock said lever when placed in a horizontal position.

I hereby dedicate the invention herein described to the free use of the public, to take effect upon the granting of a patent to me.

LAWRENCE EVANS.
